Andrew Kryczka 78d1a5ec72 Preserve overlapping file endpoint invariant ... Summary: Fix for #2833. - In `DeleteFilesInRange`, use `GetCleanInputsWithinInterval` instead of `GetOverlappingInputs` to make sure we get a clean cut set of files to delete. - In `GetCleanInputsWithinInterval`, support nullptr as `begin_key` or `end_key`. - In `GetOverlappingInputsRangeBinarySearch`, move the assertion for non-empty range away from `ExtendFileRangeWithinInterval`, which should be allowed to return an empty range (via `end_index < begin_index`).
